python-theano 1.0.3+dfsg-1 (amd64 binary) in ubuntu focal

 Theano is a Python library that allows one to define and evaluate mathematical
 expressions involving multi-dimensional arrays efficiently. It provides a
 high-level Numpy like expression language for functional description of
 calculation, rearranges expressions for speed and stability, and generates
 native machine instructions for fast calculation. Optionally, highly
 accelerated computations could be carried out on graphics cards processors.
 .
 This package contains Theano for Python 2.

 Theano development is ending: consider using Caffe or Torch instead.
